On my team i have:
Froslass @ Bright powder [Female]
Trait: snow cloak
Stats: ATK: 93 Def: 73 Sp. Atk: 89 Sp. Def: 68 Spd 109
Nature: naughty (+ Atk -Sp. def)
Ominous wind
Hail
Icy wind
Confuse ray
This is my Lead Pokemon that I am training. She is my Leader and makes up my weather during battle. I use her because she can lower the accuracy of my opponents enough and her evasiveness during hail makes her the perfect pokemon to move in as a special sweeper.

Toxicroak @ Focus band [female]
Trait: Anticipation
Stats: Atk: 152 Def: 71 Sp. Atk: 118 Sp. Def: 90 Spd:104
Nature: Lonely (+attack -Defense)
Toxic
Revenge
Return
Venoshock
This member is my physical sweeper having an attack stat on par with latios thats over 20 levels above Toxicroak but sadly all her other stats are put to shame by the entire team except gliscor and its special attack forcing Toxicroak to have to be covered by some type of move.

Latios @ nothing [male by default]
Trait: levitate
Stats: Atk: 152 Def: 130 Sp. Atk 204 Sp. Def: 178 Spd: 186
Nature: Docile (nothing affected)
Dragon pulse
Luster purge
Fly
Draco meteor
He is pretty much the mixed sweeper on the team. His attack and Sp. Atk make him perfect for mixing since his fly attack deals enough to make up for his lack of second attack.

Charizard @ Expert belt
Trait: Blaze
Stats: Atk 175 Def 161 Sp. Atk 200 Sp. Def 165 Spd 192
Nature: Bashful (affects nothing)
Flamethrower
Heat wave
Fly
Dragon claw
He is my tank pokemon; serving as my Mixed sweeper Mixed Wall (in the case I need to set up for my other pokemon) and of course pretty much any other position i didnt fill with the other 5.
This team is severely unbalanced and yet i want you to rate it! What do i need to change about this team?

Latios @ White Herb
Trait: Levitate
Evs: 252 Spe/ 252 Sat/ 4 HP
Timid Nature
- Draco Meteor
- Psyshock
- Tailwind
- Thunder Wave
So this set is a bit different from most Latios. Draco Meteor+ Whit Herb is death incarnate to most teams. Psyshock is second STAB and hit Blissey and its likes really hard at the same time as Tailwind supports and Thunder Wave cripples.
